T 0 all whom it may concern.-

Be it known that I, ARTHUR M. BURNHAM, a citizen of the United States, residing at Gardiner, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in MopWVringers, of which the following is a specification.

In order that my invention may be fully understood, Iwill proceed to describe it with reference to the accompanying drawings, in which Figure l is aperspective view of the improved mop-wringer, showing the wringingrollers pressed together and also a tub or pail in dotted lines. Fig. 2 is a side elevation, on a larger scale, with parts broken away, the rollers being represented apart by the full and pressed together by the dotted lines. Fig. 3 is a plan showing the rollers pressed together.

1 designates a base-frame, which may be of any desired shape, preferably square, and is provided with one or more upwardly-pro jecting lugs, 2, which, in connection with a thumb-screw, 3, having hearings in said frame 1, or a lug projecting therefrom, form a clamp for holding the pail or tub, as shown. Pro jecting upwardly from each corner of the base-frame 1 is a lug, 4, which forms the bearing for two parallel roclcshafts, 5, upon each of which is keyed a pair of bell-crank levers, 6 6. The upper extremities of the bell-crank levers of each pair are bent horizontally toward each other, as shown in Fig. 2, while the extremities of all four of said levers are bent slightly inward toward one common center, to wit: that of the tub, for the purpose to be hereinafter explained. Mounted between the extremities of the levers of each pair is a roller,which maybe of wood, rubber, metal or any other material which is found to be best adapted for the purpose. The lower horizontal arms of each pair of levers 6 meet about midway of the frame and are pr ferahl y formed with upwardlyproj ecting lips, 8, which bear against the under sides of steps 9,formed upon a U-shaped treadle or foot-lever, 10. The extremities of this lever extend to the side of the base-frame, and are there pivoted to the lugs 4, or to any other fixed part of the apparatus. It will be seen that when this U-shaped lever is depressed by pressure upon treadle 11 the step 9, bearing against the extremities 8 of the bell-crank levers 6, will cause the latter to rock upon their bearings in the lugs 4, and thereby bring the rollers 7 together over the tub. The object in bending the upper extremities of the bell-crank levers 6 toward a common center,as shown in Fig. 3, is to enable the use of rollers sufficiently short to be received within the top of the tub, so that when they are pressed together they will be carried below the top thereof, and thereby prevent the water from dripping upon the floor. 12 12 are lugs or pins projecting from the sides of the U-shaped lever 10, and engaging beneath the extremities 8 of the bellcrank levers 6, whereby all the levers are made to movein unison. One or more springs, 13, are employed,whieh exert their force upon some one or more of the moving parts in order to automatically separate the rollers 7 when pressure upon the treadle 11 is removed. These springs are shown as bearing upon the bell-crank levers 6; but it is obvious that this is not essential. The base-frame 1 is provided on the side upon which the treadle 11 is located with arms 14, which serve to prevent the tipping up of the apparatus by the pressure exerted in wringing the cloth.

Having thus described my invention, the following is What I claim as new therein and desire to secure by Letters Patent- 1. A mop-wringer constructed with a baseframe, paired bell crank levers fulcrumed thereto, wringcr rolls carried by the said levers, and a foot-lever acting on the bellerank levers to press the wringer-rolls together, substantially as set forth.

2. The combination of the base-frame, bellcrank levers fulcrumed thereon and carrying wringer-rolls,and a U-shaped foot-lever hearing on the bell-crank levers, substantially and for the purposes set forth.

3. In a inop-wringer, the co1nbination,\vith a base-frame and a treadle-lever projecting beyond said frame,of the arms 14, for the purpose explained.

4. In a mopwringer, the combination of a base-frame, a pair of rock -shafts jonrnaled therein, a pair of beIl-crank levers secured to each of said rock-shafts, a roller carried by each pair of bell-crank levers, and a treadlelever for operating said bell-crank levers, as explained.

5. In combination, the frame 1, the paired bell-crank levers 6 fulcrumed thereon and l having the rollers 7 the treadle-lever 10,having steps 9 and pins 12,and aretraeting device, IO all constructed and arranged substantially as set forth.
